It's no secret that one of our favorite clothing designers is Margaret Howell. Her understated, finely-tailored utilitarian clothing have been a mainstay of the UK fashion scene for more than 30 years. Americans may have yet to discover Howell's low-key chic, but the Japanese caught on early: this year marks the 30th anniversary of Howell's first boutique in the country, and she currently has almost 100 shops across Japan. Located in Tokyo's Jinnan-Shibuya district, her Tokyo flagship was designed by her longtime collaborator, William Russell of Pentagram Architects, and sports the same look and feel as his esteemed Margaret Howell shop on London's Fulham Road.
